Part A:

answer- $1.80

(20% of $1.50 is .30, so 1.50+.30=1.80)

Part B:

<em>September=$540 </em>( 1.50 times 900 is 1,350, 40% of 1,350 is 540)

<em>October=$504 </em> ( 1.80 times 700 is 1,260, 40% of 1,260 is 504)

answer=they earned more money in September; $36 more

(540-504=36)

Hope this helped!

Answer:

Area of parallelogram is 150 square ft

Step-by-step explanation:

Given the parallelogram in the figure whose height is 10 ft and base length is 15 ft.

Area of parallelogram is $base \times height$

= $15\times 10ft^2$

= 150 square ft

now we have to decompose this parallelogram into rectangles and triangles and then to determine the shape.

The given parallelogram KLMN can be decomposed into 2 triangles and one rectangle.

2 right angled triangles KPL and NOM by construction

$KL^{2}=KP^{2}+PL^{2}=10^{2}+2^{2} =100+4=104$

⇒ $KL=\sqrt104=10.2 ft=MN$ (∵ KLMN is a parallelogram)

Hence, dimension of triangles are 10 ft, 2 ft and 10.2 ft

Now rectangle KPON with dimension 15 ft and 10 ft because KP and NO are perpendiculars on LM.
